Algorithm for diagnosing accidents and leaks with unknown amplitude, taking into account interference from stochastic consumption in the gas supply system
  • The algorithm for detecting accidents and natural leaks in gas supply systems is considered. As external sources of interference, ordinary gas consumers are acting because of the stochasticity of their applications. This problem can be classified as a combined problem, which is an important case of leak diagnostics, in which both the amplitude and the noise intensity are unknown simultaneously. The most urgent task is for gas supply systems, since gas leaks can cause accidents, explosions and fires, which entail significant economic and social damage.
